Why does Toyota continue to use the term PNP switch instead of TR sensor, despite SAE's recommendation on Toyota Sequoia and Toyota Tundra?

Despite the Society of Automotive Engineers (SAE) recommending since 1996 that manufacturers use the term Neutral Safety Switch instead of Park/Neutral Position (PNP) switch, Toyota persists in referring to the TR sensor as the PNP switch.
